In short, no. Power antennas were not available on C body wagons until 67 and were front fender mounted.
Here is some information:
65 Imperial power antennas were front fender mounted and retracted fully into the fender. However there is not enough room on C body front fenders and hence they were rear quarter mounted (with a little bit sticking out above the quarter when retracted) until 67. In 67 you could get a shorty front fender power antenna which also didn't retract fully into the fender.
Imperial power antennas had a different bezel arrangement than C body power antennas as well.
